Will it be possible to have a custom field on all the confluence spaces and pages?

Hi,

Will it be possible to have a custom field (e.g: check box) on space & all the confluence pages that help in filtering the spaces and pages via Rest API? I know we have a label option. But we are looking for more user-friendly option. or if you can suggest us any other options that can make more user friendly also helps us.

Thanks
